Description

FIELD OF THE DISCLOSURE

The present disclosure is generally related to a system and method of applying globally unique identifiers to relate distributed data sources.

BACKGROUND

In general, public information sources, such as the Internet, present challenges for information retrieval. The volume of information available via the Internet grows daily, and search engine technologies have scaled dramatically to keep up with such growth. Conventionally, search engines, such as those provided by Yahoo, Google, and others, utilize data collection technologies, such as spiders, bots, and web crawlers, which are software applications that access web pages and trace hypertext links in order to generate an index of web page information. The data collected by such software applications is typically stored as pre-processed data on which search engines may operate to perform searches and to retrieve information.
Additionally, a vast amount of data exists that is not accessible to the public Internet (e.g., “dark web” data, internal data, internal application data, private data, subscription database data, other data sources, or any combination thereof). Such data can often be searched via private access interfaces, private search tools, other application program interfaces, or any combination thereof. Such information may be segregated from other information sources, requiring multiple interfaces, multiple protocols, multiple formats, and different database drivers to access the data. Accordingly, information retrieval can be complicated by the variety of data sources.
In general, software has been developed to provide “on-line analytical processing” (OLAP) for collecting, managing, processing, and presenting multidimensional data for analysis and management purposes. Typically, an OLAP interface is customized for each data source. However, such custom interfaces do not readily leverage existing, distributed data sources without significant coding. Further, when an OLAP interface is designed to access multiple data sources, either the multiple data sources are pre-processed to index the data to a searchable index or the multiple data sources are commonly controlled such that the data structures are uniform. Unfortunately, a large amount of data, for example, unstructured data and semi-structured data that is stored on the Internet, may include useful information that cannot readily be correlated to data from other sources.
Conventionally, multiple data sources may include data related by a common attribute. However, such data may not be readily correlated due to differences in data structures, in attribute labels, in data formats, in the data entered, or any combination thereof. For example, in one data source, a company name may be tagged or labeled using the term “company,” while another data source may label the data using other terms, such as “business name,” “co.,” “corporation,” other labels, or any combination thereof. Further, even when two data sources have common labels, such as “company,” the data is entered in a first data source may be entered differently from the second data source, making it difficult to correlate the data without manual intervention.

SUMMARY

In a particular embodiment, a method includes sending a text string from a source device to a destination device. The destination device includes a unique identifier repository having a plurality of globally unique identifiers mapped text strings, relationship data defining associations between the plurality of globally unique identifiers, and meta-data related to the text string. Each of the plurality of globally unique identifiers includes a data value that is shared by a plurality of data sources as an identifier associated with information related to the text string. The method further includes receiving data including one or more globally unique identifiers, associated relationship data, and associated meta-data from the destination device at the source device in response to sending the text string. Additionally, the method includes storing the received data at a memory of the source device for use in searching and relating search results received from multiple data sources.
In another particular embodiment, a system includes an interface responsive to a network and a unique identifier repository adapted to store mappings between text strings and globally unique identifiers, to store relationship data defining associations between globally unique identifiers, and to store meta-data associated with the text strings. Each globally unique identifier includes a single value that is used as an index by a plurality of data sources to identify particular information. The system further includes processing logic having access to the unique identifier repository. The processing logic is adapted to receive a text string from a source device via the network, to identify at least one globally unique identifier related to the text string at the unique identifier repository, and to send the at least one globally unique identifier, associated relationship data, and associated meta-data to the source device via the network, where the globally unique identifier and associated relationship data are for storage at the source device.
In still another particular embodiment, a system includes a unique identifier repository adapted to store mappings between data strings and globally unique identifiers, to store relationship data representing associations between globally unique identifiers, and to store associated meta-data. Each of the plurality of globally unique identifiers includes a data value that is shared by a plurality of data sources as an identifier associated with information related to the text string. The system further includes processing logic having access to the unique identifier repository and memory accessible to the processing logic. The memory includes instructions that are executable by the processing logic to receive a text string from a source device, to infer an association between the text string and a globally unique identifier from the unique identifier repository, and to send the globally unique identifier, associated relationship data, and associated meta-data to the source device for storage at a memory associated with the source device.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

In general, a system and method of creating, retrieving and using a globally unique identifier is disclosed. In a particular embodiment, a central clearinghouse is disclosed that hosts a data repository of globally unique identifiers and that is adapted to receive a text string and to identify and provide a globally unique identifier related to the text string to a destination device. The globally unique identifier can be distributed to a plurality of systems for use in retrieving search results and in correlating the search results to provide multi-dimensional results. Further, the central clearinghouse is adapted to store relationship data defining associations between globally unique identifiers as well as meta-data related to the globally unique identifiers. Such relationship data and meta-data can also be provided to the destination device.
In another example, a method is disclosed for sending a text string related to data stored at a source device to a centralized correlation system, which is adapted to determine a globally unique identifier related to the text string from a unique identifier repository. The globally unique identifier and associated relationship data and meta-data are sent to the source device, which receives and stores the globally unique identifier and its associated information at a memory related to the source. In a particular example, the memory can be included in a source device or may be accessible to the source device via a network.
FIG. 1 is a block diagram of a particular illustrative embodiment of a system 100 to map a text string to a globally unique identifier. The system 100 includes mapping logic 102 that is coupled to a unique identifier repository 104. The unique identifier repository 104 includes multiple globally unique identifiers where each globally unique identifier uniquely represents particular information. In a particular example, each globally unique identifier is mapped to a unique piece of information, such as a name of a person, a place, a business, a commercial product, a content source (such as a text file, document, database record, or any combination thereof), another piece of information, or any combination thereof. In a particular example, the globally unique identifier can be related to a proper noun, and each globally unique identifier can have a variety of associations or relationships to other globally unique identifiers. In general, each globally unique identifier can have associated relationship data and associated meta-data.
The mapping logic 102 is adapted to receive a text string 106. The mapping logic 102 may also optionally receive logical variations of the text string 108 and synonyms or terms related to the text string 110. In a particular example, heuristics may be applied to the text string 106 to identify variations that reflect common misspellings, common or possible abbreviations, and possible variants related to the text string 106.
The mapping logic 102 is adapted to identify a globally unique identifier from the unique identifier repository 104 that is related to at least one of the text string 106, the logical variations of the text string 108, and the synonyms or terms related to the text string 110. In a particular example, the mapping logic 102 may be adapted to apply statistical analysis to identify a likely globally unique identifier from a plurality of globally unique identifiers based on a context and/or other factors to select a particular globally unique identifier. The mapping logic 102 is adapted to provide the selected globally unique identifier that is associated with the text string to an output 112. In particular, the mapping logic 102 is adapted to provide the selected globally unique identifier, associated relationship data, and associated meta-data to the output 112 and/or to send the selected globally unique identifier, the associated relationship data, and the associated meta-data to a destination device.
In a particular embodiment, the mapping logic 102 and the unique identifier repository 104 may be hosted by a central correlation system, which acts as a repository and clearinghouse (registration source) for globally unique identifiers that can be used to search multiple federated data sources and to relate (correlate or join) search results. New information items can be registered with a globally unique identifier or can be provided to the mapping logic 102 to identify an existing identifier or to create a new globally unique identifier. The globally unique identifier at the output 112 can be sent to a remote device for storage and subsequent use.
In a particular example, the mapping logic 102 is adapted to ensure that each unique identifier is globally unique, at least within an available content space, so that the globally unique identifier can be relied upon to retrieve relevant information and to associate and join information from different data sources along at least one dimension. In a particular example, the globally unique identifier can serve as an edge of a data cube including information from multiple data sources and in various data structures, allowing a search system or other device to provide useful information and to organize the information in ways that may allow for visualizations and other data representations that might not otherwise be possible. To the extent that the mapping logic 102 and the unique identifier repository 104 are managed by a clearinghouse, the mapping logic 102 can guarantee uniqueness of the identifier within the known data space. Further, by using an identifier that includes 128-bits or more, the globally unique identifier is statistically likely to be unique relative to existing serial numbers or identifiers generated independently from the mapping logic 102.
FIG. 2 is a block diagram of a particular illustrative embodiment of a system 200 to relate distributed data sources using globally unique identifiers. The system 200 includes a centralized correlation system 202 that is adapted to communicate with multiple data sources 204, 206, 208 and 210 via a network 212. In a particular example, the network 212 may be a local area network, a wireless network (local or wide area), a wide area network, such as the Internet, or any combination thereof. It should be understood that the data sources 204, 206, 208, and 210 can be server systems, individual computers, stand-alone databases, or any combination thereof. In general, the data sources 204, 206, 208, and 210 can store structured data, semi-structured data (such as tagged data), unstructured (text) data, or any combination thereof.
The centralized correlation system 202 includes an interface 214 that couples the centralized correlation system 202 to the network 212. The centralized correlation system 202 further includes processing logic 216 and memory 218 accessible to the processing logic 216. In a particular example, the centralized correlation system 202 can be distributed across multiple computing systems and the memory 218 and the processing logic 216 can be distributed.
The memory 218 includes a plurality of instructions that are executable by the processing logic 216 to identify and provide a globally unique identifier for use by other systems. The memory 218 includes category identification logic 220 that is executable by the processing logic 216 to determine a category of information related to a particular text string. The memory 218 further includes an analysis module 222 that is executable by the processing logic 216 to apply heuristics to a received text string identify possible typographical errors and to reduce or limit the search. In a particular example, the analysis module 222 may be adapted to identify likely variants of a text string based on a context from which the text string is received. For example, if the text string is derived from a patent search, the analysis module 222 may infer a likely spelling based on a particular technology area. In a particular example, the analysis module 222 may also be adapted to expand a text string to include synonyms. The memory 218 further includes a unique identifier (ID) generator 224, which may be adapted to generate a statistically unique ID value, such as multiple digit number, a 128-bit or 256-bit hexadecimal value, another identifier that includes text and numbers, or any combination thereof, which may be associated with the text string to provide a globally unique identifier.
The memory 218 also includes correlation (mapping) logic 226 that is adapted receive a text string and optionally one or more synonyms and one or more variations of the text string. The correlation logic 226 is adapted to identify a globally unique identifier associated with the received data. In general, the correlation logic 226 is adapted to reduce one or more terms/synonyms/logical variations to a single globally unique identifier from one or more correlated records 230. For example, the one or more correlated records 230 can include a record 232 associated with IBM® that is associated with a globally unique identifier (e.g., globally unique identifier is 123). Additionally, the record 232 also includes other associations, such as a person “Tyron Stading=567”, where the number “567” represents another globally unique identifier. Similarly, the record 232 includes a product name (Websphere=789), where the number “789” represents another globally unique identifier. It should be understood that while the globally unique identifiers are illustrated as simple integer values, the numbers can be floating point numbers, hexadecimal numbers, or other types of numbers. Further, while the number is shown as a three-digit number, it should be understood that any number of digits may be used. Further, in a particular embodiment, the correlated records 230 may store multiple globally unique identifiers that a particular globally unique identifier may have associated relationship data and meta-data that relate the particular globally unique identifier to other globally unique identifiers and to other related information.
Further, the memory 218 includes a centralized correlation output generator 228, which may be used to generate an output in a form that can be used by a requesting device. For example, if the requesting device that sends the text string is a database having a particular extensible markup language (XML) schema, the centralized correlation output generator 228 may be adapted to provide the globally unique identifier to the requesting device in an XML format.
In this particular example, the data sources 204, 206, 208, and 210 include the same information entered in different ways. For example, the company name “IBM” is represented in four different ways. Similarly, the individual's name “Tyron Stading” is represented in four different ways. In general, even within a single enterprise, unless strict data entry guidelines are enforced, data can be made difficult to retrieve and correlate because the data is entered differently at each data source.
In a particular embodiment, the data source 206 sends a text string “Int. Bus. Machines” to the centralized correlation system 202 via the network 212. The analysis module 222 can be used by the processing logic 216 to expand the text string to include multiple possible variations. The correlation logic 226 is adapted to identify the record 232 in the correlated records 230 and to determine that the received text string is correlated to the globally unique identifier 123. In this particular example, the centralized correlation output generator 228 provides the globally unique identifier 123 to the data source 206 for inclusion and association with its existing records. Additionally, the centralized correlation output generator 228 can provide relationship data representing associations between the globally unique identifier 123 and other identifiers to the data source 206. Further, the centralized correlation output generator 228 can provide meta-data associated with the globally unique identifier and/or with the relationship data.
In a particular example, by populating multiple data sources with the globally unique identifier (GUID), each of the data sources may be searched using the GUID to retrieve desired information. Further, the GUID can be used to join data received from multiple data sources. For example, the search results from the multiple data sources 204, 206, 208, and 210 can be organized into a data cube with the GUID serving as an edge of the cube. In a particular example, the GUID can be used to join information from multiple data sources, so that the search results can be mined in multiple dimensions. Further, if the multiple data sources 204, 206, 208, and 210 also store the associated meta-data, the search results can be enriched with the meta-data to provide multiple dimension of information.
FIG. 3 is a block diagram of a representative embodiment of a data source 300 that is updated to include a globally unique identifier for existing records. In a particular example, a data source 300, such as the data source 204 illustrated in FIG. 2, includes a plurality of data records 204A, which include an index number 302, a company name 304, and other information 306. In a particular example, the index number 302 may represent a serial number or record number that is unique to the particular data source and which can be used to retrieve individual records.
A host associated with the data source 204 may submit a text string, such as the company name 304, to a centralized correlation server. The centralized correlation server returns a globally unique identifier related to the text string. The globally unique identifier can be stored in the updated plurality of records 204B as a globally unique identifier 310. In general, once the data source is updated with the globally unique identifier 310, its data can be readily joined and correlated with data from other sources using the globally unique identifier 310.
It should be understood that the plurality of records 204B represent only one way of modifying the source information with the received globally unique identifier. Further, if associated relationship data and associated meta-data are received at the data source 300, such relationship data and associated meta-data are not reflected in the updated plurality of records 204B. In this particular instance, such relationship data and associated meta-data may be stored elsewhere or may be disregarded at the data source 300.
FIG. 4 is a block diagram of a second particular illustrative embodiment of a data source 400 that is updated to include globally unique identifiers for multiple fields within existing data, which may be stored in one or more data sources. The data source 400 includes general corporation information 402 including a company identifier that relates to a globally unique identifier. The data source 400 further includes product information 404 that relates to a product identifier that is a globally unique identifier. Further, the data source includes employee data 408 that includes salary information for particular employees that is related to a globally unique identifier. The data source 400 may also include a table 406 that has a globally unique identifier related to each field. In this instance, each record has a row identifier. Within the first row, for example, the row identifier includes a product name with an associated globally unique identifier (product identifier), a company name with an associated globally unique identifier (company identifier), and a person's name with an associated globally unique identifier (person identifier). The table 406 can include other information, which can be readily associated with corresponding globally unique identifiers located in other data stores at the data source 400 or at a remote data source.
In a particular embodiment, the globally unique identifiers in the table 406 can be exploited to assemble distributed information from various sources to join related information. The table 406 defines an association between the various globally unique identifiers that allows meta-information to be retrieved from sources where the meta-information is unrelated to a particular query. In a particular example, the table 406 represents miniature dimensions between pieces of information in the table 406 as well as data associated with the other data sources 402, 404 and 408, which can be mined using such globally unique identifiers, either locally or via a centralized correlations system.
FIG. 5 is a representative diagram of a particular illustrative example of an extensible markup language (XML) text portion 500 including particular fields and data before and after updating with globally unique identifiers and associated metadata. Before updating from a central correlations system or from a local data source, at 502, particular data is tagged using XML identifiers. For example, a row identifier “ABC” is linked to a product “WebSphere®,” to a company name “IBM®,” and to a person “Tyron Stading.” The XML text portion 502 can be sent to a central correlations system.
At 504, the tagged information is returned from the central correlations system or from the local data source along with globally unique identifiers associated with the particular product, company, and person. Further, metadata can be provided along with the globally unique identifiers, such as revenue and retail data associated with the product, revenue and employee information associated with the company, and location and salary information associated with the person. The globally unique identifiers and the metadata may be stored at a data source, such as the table 406 of the data source 400 illustrated in FIG. 4.
FIG. 6 is a diagram of a particular illustrative example of a document 600 including text data before and after updating with meta-data using globally unique identifiers. Prior to updating, the document 602 includes person information “Tyron Stading,” product information “Websphere®,” company information “IBM®,” title information, and text information.
After updating from a central correlations server or from a local data source, the document 604 includes salary metadata associated with the person information, revenue and other data associated with the product, and company revenue and other company data related to the company. If relationships, meta-data, or any combination thereof, existed for the title and the text, such information could be embedded into the document 604 as well.
In general, the globally unique identifiers can be used to populate documents, reports, and data sources with related information based on associations between globally unique identifiers. In a particular example, miniature dimensions exist between pieces of information in a table that can be mined using such globally unique identifiers, either locally or via a centralized correlations system. Once the globally unique identifiers are stored locally, the information can be used to enrich existing documents and reports with information that might otherwise be difficult to locate and/or that the particular individual might not otherwise be aware of.
FIG. 7 is a block diagram of a second particular illustrative embodiment of a system 700 to relate distributed data sources globally unique identifiers. The system 700 includes a central correlation server 702 coupled to a unique identifier repository 703. The central correlation server 702 communicates with a search system 704 via a network 706. Further, the central correlation server 702 is communicatively coupled to external data systems 708 via the network 706. The external data systems 708 may be coupled to external data 742. In a particular illustrative embodiment, the network 706 may be a public network (such as the Internet), a private network (such as a corporate intranet, a virtual private network, an enterprise system, or any combination thereof), or any combination thereof. In general, multiple remote devices, such as the user device 750, can communicate with the search system 704 via the network 706. In a particular illustrative embodiment, the user device 750 may represent any device, such as a computer, a web-enabled mobile phone, a personal digital assistant (PDA), a set-top box device, or any combination thereof, that has access to the Internet and that is capable of executing an Internet browser application.
Additionally, the search system 704 may communicate with one or more external data systems 708, such as web sites, commercial databases, libraries, government sites, internal or private data sources, user-generated data (i.e. meta-data, user-tagged data, web logs (blogs), or other user-generated data), other data sources, or any combination thereof. Such external data systems 708 may include structured data (such as pre-processed data, database records, other structured data, or any combination thereof), semi-structured data (such as tagged data, e.g., hypertext markup language (HTML); extensible markup language (XML); formatted data; or any combination thereof), and unstructured data (such as text). In a particular illustrative embodiment, the structured data may include indexed data, such as data that is assembled using an automated software application, such as a spider, a “bot,” a software agent, or other software, which commonly is used by search engine applications to index data sources for later retrieval. The search system 704 can communicate via the network 706 with the user device 702, with the external data sources 708, and with other devices via a firewall 710, which provides security to the search system 704 to prevent undesired intrusions.
The search system 704 includes an interface 712 that is responsive to the network 706, processing logic 714 that is coupled to the interface 712, and memory 716 that is accessible to the processing logic 714. In a particular illustrative embodiment, the search system 704 may include multiple servers having separate processors and memory devices, which may cooperate to provide the search system 704. The memory 716 includes a data acquisition module 720, including an extract-transform-load (ETL) feature, which is executable by the processing logic 714 to acquire data from the external data systems 708 and to extract, transform and load the acquired data into one or more data stores, including document data storage 734. In a particular illustrative embodiment, the ETL feature of the data acquisition module 720 can identify missing information (such as missing fields, missing meta-data, garbled information, omitted data, or any combination thereof) and can make probabilistic determinations to assign values in lieu of the missing information. For example, in a particular illustrative embodiment, the data acquisition module 720 identifies missing assignee information associated with a particular patent and makes a probabilistic determination to extrapolate a likely assignee of the patent.
The memory 716 may also include a search module 722 having an ETL feature. The search module 722 can be executed by the processing logic 714 to receive a query, to generate queries to other search engines and to one or more of the other data sources 708, and to extract data from search results (using the ETL feature). In a particular illustrative embodiment, the search module 722 may include a query learner to monitor user interactions with search results, to receive user input related to relevance of selected search results, to determine a desired result based on the user input and the initial query, and to generate new queries based on determining the desired result.
The memory 716 may also include a data storage module 724 that is executable by the processing logic 714 to store retrieved data, metadata, statistics, other data, or any combination thereof. The data storage module 724 may also be adapted to store globally unique identifiers and associated relationships in one or more of a user data storage 732, a document data storage 734, a financial data storage 736, a classification information data storage 738, other data storage 740, or any combination thereof. The user data storage 732 can include user-provided tags (descriptions, meta-data, categories, or other information) related to documents or data associated with other stored information. The user data storage 732 can also include correlations to user-created data, such as spreadsheet data, table data, document data, web log (blog) data, other data, or any combination thereof.
The document data storage 734 can include meta-data about documents (e.g., ownership data, location data, authorship data, date information, classification data, publication/source data, relationship/reference data, embedded tags, other data, or any combination thereof). In a particular illustrative, non-limiting embodiment, the document data storage 734 can include data related to particular structured documents, such as patents, Published patent applications, and other structured documents. In such an instance, the document data storage 734 can include data related to the title, the inventors, the assignee, the priority data, the claims (e.g., number of claims, number of independent claims, claim terms, types of claims, other information, or any combination thereof), the Abstract (e.g., text of the abstract, keywords extracted from the abstract, a number of words in the Abstract, other information related to the abstract, or any combination thereof), the file history (e.g., whether claims were amended during prosecution, a list of cited references, links to file wrapper documents, other information, or any combination thereof), excerpts from the specification that relate to search terms, or any combination thereof. The document data storage 734 may also include various documents, such as Patents, journals, research papers, white papers, product documents, web sites (i.e. as a stored source file), articles, press releases, books, manuals, presentations, reports, sales information, any other document containing text, or any combination thereof.
In a particular illustrative embodiment, the financial data storage 736 can include revenues, profits, credit history, price-to-earnings (P/E) ratio, industry data for classification of tax records, Securities and Exchange Commission (SEC) reports, stock prices, stock trends, other financial data, or any combination thereof, which is related to each particular company. In another particular illustrative embodiment, the financial data storage 736 may also include financial data related to individuals, organizations, associations, other entities that have financial information, or any combination thereof. In still another particular illustrative embodiment, the financial data storage 736 can include other financial information that can be related to any category of interest.
In a particular illustrative embodiment, particular financial data may be added to the financial data storage 736 to provide customized data to a particular enterprise.

Continuing to 1404, the received data are correlated to a normalized data mapping for previously registered data values, where the normalized data mapping includes a plurality of unique identifiers mapped to a respective plurality of data values and where each data value is mapped to a unique identifier of the plurality of identifiers. In a particular embodiment, the data are normalized by expanding the data to include logical variations and synonyms, which can be searched within the plurality of identifiers to retrieve one or more globally unique identifiers.
Proceeding to 1406, new identifiers are automatically generated within the normalized data mapping for previously unregistered values. For example, after searching, if no globally unique identifier is found, a new globally unique identifier may be generated for the data, and an interface may be provided to allow a user, such as an operator, administer, or other user to supplement the record with association information. In a particular example, the interface may be a web-interface, such as a Wiki-type web-interface that allows any registered user to supplement a particular registered information item. Advancing to 1408, the normalized data mapping is distributed to the destination device. In a particular example, if the globally unique identifier is new, few if any relationship data may be available. However, over time, existing globally unique identifiers may have relationship data that defines associations between globally unique identifiers. In a particular embodiment, the globally unique identifier and associated relationship data may be provided to the destination device (such as a user device) in response to receiving a query.

In general, the graphical user interface 1600 may be accessed by users to updated and modify associated relationships and meta-data associated with a particular globally unique identifier. In a particular example, the graphical user interface 1600 may be accessible to the general public, similar to a WIKI-type web site to allow users to supplement available information related to the globally unique identifier. In another embodiment, the graphical user interface 1600 may be accessible only to authorized users.
In conjunction with the systems, methods and interfaces described above with respect to FIGS. 1-16, a system is disclosed to create, store and share globally unique identifiers that can be used to retrieve and join (correlate) information retrieved from multiple data sources.
